Proceedings of the fourth ACM conference on Wireless network security

It is our great pleasure to welcome you to the 2011 ACM Conference on Wireless Network Security -- WiSec'11. This year's conference continues the tradition of being the premier forum for presenting research results and experience reports on cutting edge topics in wireless network security, where results on the attacks and threats facing wireless communication as well as techniques to address them are presented, and new directions for future research and development can be identified. Settings of interest include cellular, metropolitan, mesh, local area, personal-area, home, vehicular, sensor, ad hoc, satellite, and underwater networks as well as cognitive radio and RFID. ACM WiSec gives researchers and practitioners a unique opportunity to share their perspectives with others interested in the various aspects of wireless network security. The call for papers attracted 87 submissions from Asia, Canada, Europe, and the United States. The program committee accepted ten full papers and nine short papers that cover a variety of topics including address space randomization for mobile devices, interactive decryption of DECT phone calls, jamming attacks on wireless broadcast communications, lightweight remote attestation, or inferring users' online activities through traffic analysis to name a few. In addition, the program includes a panel organized by Srdjan Capcun on the subject 'What constitutes good research in wireless security?' and two keynote speeches from academia and industry: Ingrid Verbauwhede (K.U. Leuven) is giving a talk on 'Low budget cryptography to enable wireless network security' and Jan Muller (Airbus) provides insights into 'Wireless Sensor Applications in Aviation -- Applications and Design Drivers'. We hope that these proceedings will serve as a valuable reference for security researchers and developers.
